OF ROME, GEORGIA MECHANISM FOR GIVING A COMBINED ROTARY AND RECIPROCATING MOTION TO CHURN-DASHERS.

SPECIFICATION formingpart of Letters Patent No. 241,799, dated May 24, 1881.

Application filed March 8, 1881.

To all whom it may concern:

Be it known that I, WILLIAM L. GORDON, of Rome, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Mechanism for Giving a 00mbined Rotary and Reciprocating Motion to Ohurn-Dashers; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,which form a part of this specification.

Figure 1 is a top plan. Fig. 2 is a vertical sectional view, and Fig. 3 is a view of the dasher detached.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to that class of churns in which the dasher has a combined rotary and vertical reciprocating motion and it consists, especially, in the improved construction of the operating mechanism, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A represents the base,which is provided with two uprights, B 0, connected by a cross piece or brace, D. The upright B is provided, above the brace D, with a slot or notch, E, in which is pivoted a lever, F, extending through a vertical slot, G, in the upright O. The brace D is provided with a central vertical bearing, H,for the stem or shaft I of the dasher J, which consists of two cross-pieces, K, secured X-wise at the lower end of the stem or shaft, and provided on opposite sides with vertical pins or pegs L. By this construction of the dasher it is specially adapted to cut and agitate the cream by the vertical reciprocating and rotary motion, which it is the object of the operating mechanism to produce.

A thermometer, M, is secured to the side of the dasher for the purpose of gaging the temperature of the cream.

N is a balancewheel, provided with a radial slot, 0, by which it may be adjusted in a horizontal position upon the dasher-stem, where it is secured by a pin or key,]?, or any other suitable means.

Q Q are ropes or cords, the ends of which are secured to opposite sides of the collar of (No model.)

the fly-wheel, from whence they pass through openings R in the brace D, at some distance from the dasher-stem. The ends of the cords are then joined, as shown, under a stud, S, which prevents them from being exposed to the friction of the dasher-stem. The upper end of the latter is fitted in a recess or groove, T, in the under side of lever F, as shown.

U is a rubber spring, fitted adjustably upon uprightO above the lever F, to receive the force of the upstroke of the latter and impart additional impetus to the operation. The end of the lever may be connected by a cord,V, with the end of a treadle, W, hinged at the end of the base; or the lever may be operated by hand, if preferred.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation of my invention will be readily understood. The vessel containing the cream having been placed upon base A, between the uprights B O, the dasher and fly-wheel are turned until the cords Q Q are wound partly upon the dasher-stem. By operating lever F the dasher is now vertically reciprocated, the arrangementot' the fly-wheel and cords serving to rotate or oscillate the dasher with sufficient force or impetus to lift it when the lever is raised, when, by a pressure of the lever, the motion is continued.

The construction of this device is simple and inexpensive, and it may be easily operated with good results.

Having thus described my invention, 1 claim and desire to secure by Letters Patent of the United States-- 1. The combination,with the dasher I, having slotted fly-wheel N, of the lever F, slotted upright O, having spring U, and operatingcords Q Qflls herein described,for the purpose set forth.

2. The combination, with the dasher J, of the fly-wheel N, having slot 0, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM L. GORDON.
